The Vital Role of Iron in the Human Body

The Vital Role of Iron in the Human Body

Iron is considered one of the most important elements in the human body; it has an important role for the survival of the vital functions of the human body. It is a transitional element that can give and receive electrons, so it enables the breathing process and the production of energy for the body. Iron is one of the most important elements in nature and its deficiency in the body causes anemia; iron deficiency is one of the most common causes of anemia in the world.

The normal rate of iron in an adult human ranges between approximately 2000-3000 milligrams. The main source of iron is found in red blood cells in the form of hemoglobin, which is responsible for transporting oxygen to complete the respiration process. The rest of the amount of iron is stored in the liver, spleen, and bone marrow.

Symptoms of Iron Deficiency: Pale Skin, Dizziness, Fatigue, Apnea, and Mouth Swelling

Due to the importance of iron in the human body and its pivotal function for the organs and systems of the body, its deficiency causes many health problems and malfunctions in the functions of the body’s systems, so it is important to monitor the amount of iron in the body. Its deficiency has several symptoms, including:

Pale skin

One of the most famous symptoms of iron deficiency in the body is paleness of the face and skin. Hemoglobin is responsible for giving red blood cells their red color, and it is also responsible for giving the skin its healthy pink color. When hemoglobin production decreases, the skin becomes pale. The pallor may appear clearly in certain areas of the body, such as the gums, the inner area of the lips, eyelids, and nails. Skin pallor is a symptom of moderate and severe anemia.

Dizziness and headache

Iron deficiency can cause frequent headaches and dizziness. This happens because insufficient amounts of oxygen reach the brain, and this leads to swelling in the blood vessels in the brain that results in a headache. If these headaches and dizziness are frequent, it may be a symptom of iron deficiency.

Constant feeling of fatigue and stress

The feeling of fatigue and stress is one of the most common symptoms of iron deficiency; it appears for most people with iron deficiency. The feeling of stress and fatigue appears as a result of the tissue and muscles do not get the oxygen and energy they need. Thus, people with iron deficiency often feel bad mood, in addition to a general feeling of weakness, difficulty in concentrating, and lack of productivity.


The person with iron deficiency feels out of breath when the levels of Hemoglobin decrease in the body. This means that the tissues and muscles do not get enough oxygen to carry out activities; this causes acceleration and shortness of breath as a result of the body’s attempt to obtain enough oxygen.

Swelling and burning in the mouth and tongue

If you suffer from iron deficiency and anemia, symptoms may appear in the form of swelling and burning in the mouth and gums. You may notice that the tongue is swollen, inflamed, pale in color, and abnormally smooth. These are symptoms of iron deficiency. Iron deficiency may also cause general dry mouth, cracks or red inflammation at the corners of the lips, and even blisters in the mouth.

Dietary Strategies to Increase Iron Levels: Foods Rich in Iron and Vitamin C

If you recognize any of these symptoms, you often suffer from iron deficiency in the blood or anemia, so you must follow some important steps and recipes to restore the balance of iron in the blood again, including:

Choose foods rich in iron

Always include in your diet foods rich in iron, such as red meat, seafood, legumes, spinach, raisins, and apricots. The body absorbs iron from meat more than any other sources, and if you are a vegetarian, you may need to increase iron-rich plant foods to absorb the same amount of iron as someone who eats meat.

Choose foods rich in vitamin C

If you want to increase the percentage of iron in the blood and increase the ability of the body to absorb iron, you should drink lemon juice or eat other foods rich in vitamin C. Vitamin C is found in acidic juices, including orange juice, which helps the body to absorb iron better. We also can find vitamin C in broccoli, grapefruit, kiwi, leafy vegetables, melons, oranges, peppers, strawberries, tangerines, and tomatoes.
